How to Revise for Mock Exams: A 4-Week Plan for GCSE and A-level
To revise for mock exams, start four weeks out. In week 1, list every topic and rate it red, amber or green. In weeks 2 and 3, revise red and amber topics with active recall and spaced reviews. In week 4, sit timed past papers and fix the gaps. Mocks are a diagnosis, not the final result.
This guide plans a whole mock season across several subjects. For spacing the reviews of each single topic, see the 2-3-5-7 revision method, which fits inside weeks 1 to 3 of this plan.
What are mock exams for?
Mocks are practice exams set by your school, usually built from past or specimen papers from your exam board and sat in exam conditions. They do not count towards your final GCSE or A-level grades. They are still useful, for you and for your teachers:
- For you, they show what you can recall under time pressure, which is different from what you recognise in your notes.
- For your teachers, they show what to reteach before the real exams.
- For some decisions, schools may use mock results as one input, for example for GCSE tier entry or A-level predicted grades. Policies differ between schools, so ask your teachers what your mocks are used for.
So revise properly, but treat a weak mock as information. The most useful thing a mock can give you is a list of what to fix.
How do you choose what to revise first?
Start from the list of topics, not from your notes. Ask each teacher which topics the mock covers, since a mock does not always cover the whole course. Then open the specification for each subject. Exam boards such as AQA, Pearson Edexcel and OCR publish them on their websites, and they list every topic you can be examined on. Rate each topic with a traffic light:
| Rating | What it means | What to do |
|---|---|---|
| Red | You cannot explain it or answer a question on it without your notes | Relearn it from your notes or textbook, then review it with recall several times |
| Amber | You know parts of it but make mistakes in exam questions | Recall first, then exam-style questions on that topic |
| Green | You can answer exam questions on it without help | One mixed review and a few past-paper questions |
Be strict: rate a topic green only if you have tested yourself on it, not because the notes look familiar. A quick check is to write down everything you remember about the topic on a blank page for five minutes, the blurting method. A thin page means amber or red.
What does a 4-week mock revision plan look like?
Each week has one job. The daily amount depends on how many subjects you have and what else is going on at school, so the plan sets the order, not the hours.
| Week | Goal | What you do |
|---|---|---|
| 1 | Map and start | Rate every topic red, amber or green. Collect past papers and mark schemes. Start relearning the first red topics and write questions or flashcards for each. |
| 2 | Red topics | Learn one or two red topics a day. Review each with recall over the following days, for example on days 2, 3, 5 and 7. |
| 3 | Amber topics | Recall plus exam-style questions on amber topics. Keep reviewing last week’s red topics. |
| 4 | Exam practice | Timed papers or sections, marked with the mark scheme. Log every lost mark and fix the gaps. Keep the last two days light. |
Here is how that could look for a Year 11 student with mocks in biology, history and maths:
- Week 1: one evening per subject to rate topics. Red topics: enzymes and photosynthesis in biology, the Treaty of Versailles in history, simultaneous equations in maths. The student writes flashcards for the biology terms and a list of questions for history.
- Week 2: enzymes on Monday, the Treaty of Versailles on Tuesday, simultaneous equations on Wednesday, photosynthesis on Thursday, with short recall reviews of each on the following days. Maths reviews are new problems, not rereading the worked examples.
- Week 3: amber topics, such as cell transport and the League of Nations, with two or three exam-style questions each. Red topics from week 2 come back for their last reviews.
- Week 4: one timed paper or half-paper per subject, marked the same day. Every lost mark goes into a log, and the next session starts with those questions.
If you have less time, compress rather than skip a stage. The next section shows the same plan in two weeks.
How do you revise for mocks in two weeks?
Keep all four stages and make each one shorter: one evening to map your topics, about a week on red topics, then most of the second week on amber topics and timed past papers. You will not relearn everything in fourteen days, so the traffic-light rating decides where your time goes.
| Days | Goal | What you do |
|---|---|---|
| Day 1 | Map | Ask which topics each mock covers. Rate every topic red, amber or green, and find one or two past papers with mark schemes per subject. |
| Days 2 to 6 | Red topics | Relearn one or two red topics a day, mixing subjects. End each session by blurting the topic with your notes closed, and start the next one with five minutes of recall on the day before. |
| Day 7 | Check | No new topics. Test yourself on everything from days 2 to 6. Whatever you still cannot answer stays red and comes back on day 12. |
| Days 8 to 10 | Amber topics | Recall plus two or three exam-style questions per amber topic. Sit one timed section per subject, mark it with the mark scheme and start your error log. |
| Days 11 and 12 | Past papers | Timed papers or half-papers, marked the same day. Add every lost mark to the log, and review the topics still rated red. |
| Days 13 and 14 | Fix and rest | Work only from your error log and missed flashcards. Keep the evening before the first mock light. |
With two weeks, cut whatever does not test you: rewriting notes neatly, colour-coding and long summaries can wait. Green topics get past-paper questions only. If your mocks are spread over several days, sit each subject’s past paper a few days before that subject’s mock rather than all at once.
Which revision methods work best for mocks?
Methods that make you produce answers from memory. In a review of ten study techniques, Dunlosky and colleagues (2013) rated practice testing and distributed practice (spacing) as high utility, and rereading and highlighting as low utility. In a classic experiment, Roediger and Karpicke (2006) found that students who practised recalling a passage remembered more of it days later than students who reread it, even though rereading did slightly better on a test five minutes afterwards. That is the trap before mocks: rereading feels productive on the day and fades by the exam.
- Blurting suits connected topics such as history causes or biology processes. It shows what you can produce without prompts.
- Flashcards suit definitions, key terms, dates, equations and quotations. How to make flashcards that test understanding shows how to word them so they test more than recognition.
- Past-paper questions test whether you can use what you know in the form the exam asks for, within the time. Mark them with the mark scheme, not from memory.
- Spaced reviews bring each topic back after a gap rather than in one long session. How to space your study sessions explains how to choose the gaps.
All four are forms of retrieval practice. Active recall for students explains why that matters more than the exact method you pick.
What should you do the day before a mock?
- Review, do not learn. Go through your missed flashcards and your error log for that subject. A new topic the night before rarely sticks.
- Do one short recall round. Blurt the two or three topics you are least sure of, then check them.
- Check the details. Time, room, which paper it is, and the equipment you need: pens, a calculator if allowed, a ruler, a clear pencil case if your school asks for one.
- Stop at a sensible time. Arriving rested will help you more than a late extra hour of rereading.
What should you do with your mock results?
The grade tells you where you are; the marked paper tells you what to do next. Go through each paper with the mark scheme and log every lost mark with its cause:
| Question | Marks lost | Why | Fix |
|---|---|---|---|
| Biology 4b | 2 | Knowledge gap: mixed up the effect of temperature and pH on enzymes | Two new flashcards, review on days 2, 3, 5 and 7 |
| History 3 | 4 | Exam technique: described events but did not explain causes | Practise two more explain questions using the mark scheme wording |
| Maths 12 | 3 | Timing: did not reach the question | Timed half-papers; move on after a set time per mark |
| Maths 7 | 1 | Misread the question: gave the answer in the wrong units | Underline what the question asks for before answering |
Then look for patterns. If most marks went on knowledge gaps, the next revision cycle starts with those topics, rated red again. If they went on technique or timing, you need more past-paper practice rather than more content. Exam boards also publish examiner reports on past papers, which describe the mistakes many students make on each question.
Common questions
When should you start revising for mocks?
Around four weeks before the first mock gives you time to find your weak topics, revise them more than once and still sit a few timed past papers. If you find out about your mocks later, start with the traffic-light rating as soon as you know which topics they cover.
Is two weeks enough to revise for mocks?
Yes, if you focus on weak topics rather than everything. Spend one evening rating topics, about a week relearning red topics with recall, and most of the second week on amber topics and timed past papers. Green topics only need some past-paper questions.
Do mock exam results matter?
They do not count towards your final GCSE or A-level grades, but schools use them. Teachers use the results to decide what to reteach, and some schools also use them for tier entry or predicted grades. Ask your teachers what your mocks are used for.
Should I revise everything for my mocks?
Not equally. Ask which topics each mock covers, rate them red, amber or green, and spend most of your time on red and amber. Green topics need one mixed review and some past-paper questions, not a full relearn.
What should I do if I do badly in my mocks?
Go through each paper with the mark scheme and write down why you lost each mark: a knowledge gap, a misread question, timing or exam technique. That list is your revision plan for the real exams, and it is more useful than the grade itself.
Can I use the 2-3-5-7 method to revise for mocks?
Yes. Use it for red and amber topics in weeks 1 to 3: learn a topic, then review it on days 2, 3, 5 and 7. Leave the final week for timed past papers and the gaps they show.
